Core Viewpoint - The etching silicon components are essential consumables in wafer manufacturing, with silicon electrodes and silicon rings being the primary products. The shift from traditional etching methods to plasma etching has improved product yield and quality due to the superior properties of silicon materials compared to ceramics [1][3][4]. Industry Status Analysis - The etching silicon components industry is highly concentrated, with over twenty manufacturers globally, primarily located in the US, South Korea, and Japan. Key players include Silfex Inc., Hana Materials Inc., and Mitsubishi Materials. The Chinese market is rapidly growing, with local companies like Ningxia Shunyu Juxin and Jinzhou Shengong Semiconductor entering the field [3][4]. Product Lifecycle - In the international supply chain, silicon components are in the "mature phase," while in the Chinese market, they are still in the "introduction phase." The products are characterized by a wide variety and small batch sizes, with consumption depending on the types of plasma etching machines and manufacturing processes used by integrated circuit manufacturers [4]. Technology and Application - As advanced processes move towards 3 nm and below, the requirements for silicon components' purity, crystal orientation uniformity, and surface roughness are increasing. Mainstream products need to achieve over 9N purity, with metal ion contamination controlled at the ppb level. The demand for large-sized silicon rings and electrodes (300 mm and above) is rising, with some companies researching 450 mm components for future wafer size evolution [5][19]. Supply Chain Dynamics - Geopolitical factors are driving regions like Europe, the US, Japan, and South Korea to accelerate local production to reduce reliance on single supply sources. Chinese manufacturers are also capturing market share, although they face technical challenges in high-purity and large-size products. Future trends indicate a shift towards higher purity and more complex structures in silicon components [6][20]. Global Market Scale - The global market for etching silicon components is projected to reach $1.727 billion by 2024 and $2.771 billion by 2031, with a CAGR of 7.27% from 2025 to 2031. The Chinese market is expected to grow from $176 million in 2024 to $349 million by 2031, increasing its global market share from 10.24% to 12.6% [11][12]. Regional Market Insights - North America is the largest consumer market, accounting for 24.77% of the market share in 2024, followed by Japan, Taiwan, and South Korea. The Chinese market is anticipated to grow the fastest, with a CAGR of approximately 10.33% from 2025 to 2031 [13][14]. Production Insights - North America, South Korea, and Japan are the top three production regions, holding 51.4%, 19.15%, and 18.73% of the market share in 2024. China's share is expected to increase from 7.5% in 2024 to 12.55% by 2031 [14]. Product Type Distribution - In 2024, silicon rings and silicon electrodes are projected to hold 53.1% and 46.9% of the market share, respectively. OEM customers are expected to account for about 68% of the market, with a CAGR of 7.22% in the coming years [15][16]. Competitive Landscape - The core manufacturers in the global etching silicon components market include Silfex Inc., Hana Materials Inc., and Mitsubishi Materials, with the top ten manufacturers holding over 90% of the market share in 2024 [16].
